PTUNING: 501WHP 377WTQ 20psi Stock Motor PTUNING Spec-SS GTX3076R Turbo System
 

So we finally got around to dyno tuning our PTUNING FR-S with some corn juice. Although, we would have definitely made more power with E85, the numbers we achieved with E67 were pretty fantastic. Trying to find true E85 in the DMV area this time of year is nearly impossible.

Please note that, as always, all the dyno numbers that we post are uncorrected Dyno Dynamics dyno numbers. A Dyno Dynamics Dyno reads roughly 10-12 percent lower than that of a typical Dynojet.

With that said, here is what we tested:

Ecutek ProEcu RaceROM w/Flex Fuel enabled
PTUNING Spec-SS Turbo System with GTX3076R upgrade
PTUNING FR-S/BRZ Fueling Package (FIC 770cc)
PTUNING DS-333 Modular Polished T304SS 3" V-Band Turbo-back Exhaust System, 4" Tips (Dual Mufflers)
PTUNING Spec-RS 4-to-1 Equal-Length Race Header - Polished T304SS, Double-slip Racing Merge Collectors - (Prototype, In-development)
PTUNING Spec-RS Flex Fuel Return-Style Fuel System w/Racing Swirl Pot & Walbro 485LPH fuel pump - (Prototype, In-development)

Things to note:

- We always dyno our cars through the supplied air filter/intake and out the exhaust tips. No filter-less turbos, cutouts, dropped exhausts, etc.
- We also retained our standard included recirculated WG dump tube set-up. We'd expect our dump to atmosphere WG option to gain another 10-15whp at this power level.
- Our analog DD Dyno uses a standard 4:3 screen vs some newer 16:9 monitors. Keep this in mind when commenting on the shape of the power curve compared to dyno printouts that are landscape view.

180+wtq by 2.5k rpms
215+wtq by 3k rpms
260+wtq by 4.5k rpms
Usable power up to 8k rpms

Other dyno numbers we achieved during our dyno tuning session:

335whp 254wtq at 10.5psi on 93 pump gas
384whp 291wtq at 10.5psi on E67

We'll post our dyno videos on Monday and hopefully a street vid sometime next week, weather permitting.

Very promising, only from E67!! Someone should bite the bullet and ship you guys some E85 from a more accessible point in the US :thumbsup: what do the double slip race merge collectors do?

That would be nice! :D

As soon as this crazy winter is over, I'm sure the fuel distribution centers will stop distributing E60-E70 winter blends to our area and bring out regular E85.

The doubles-slip merge collectors are often used in race cars to allow for proper heat expansion without the need for flex sections on the header. Why are they not used more often on this platform? They're uber expensive to implement properly vs formed and welded merge collectors.

So if your making one in its prototype phase...I'm crossing my fingers it stays under the 4 digit mark >.< then again I have no idea how much the formed and welded merge collectors costs.

Great job! :clap: Would also like to see the dyno of the pump 93.

Awesome work! 355 on pump @ 10psi is impressive!

Is that still the exedy stage 1 clutch on this car? :)

Nice, can you post the graph showing the CF on it?


Basically you are saying this GTX30r is making 400whp on a dynojet on 10.5 psi and 93 and 560ish on 20psi e85?

Very nice

Ya agreed nice numbers

Was the gtx3076 using the 0.63 or 0.86?

impressive numbers on 93 octane, hope to see one of those dynos soon

Lovin' the pump gas numbers!
